1. A heat exchanger module comprising:
a first block of a first heat exchanger, which is formed as a liquid-cooled condenser, the first block having first fluid channels for a refrigerant and having second fluid channels for a first liquid coolant;
a second block of a second heat exchanger, which is formed as a liquid-cooled chiller, the second block having third fluid channels for the refrigerant and fourth fluid channels for a second liquid coolant; and
an expansion valve,
wherein the first block, the second block, and the expansion valve are formed as an interconnected module,
wherein the first block has a first refrigerant inlet and a first refrigerant outlet and the second block has a second refrigerant inlet, a first refrigerant passage channel, a second refrigerant outlet and a third refrigerant inlet and a third refrigerant outlet,
wherein the expansion valve has a fourth refrigerant inlet and a fourth refrigerant outlet, and
wherein the first refrigerant outlet of the first block is in fluid connection with the second refrigerant inlet of the second block, the second refrigerant inlet of the second block is in fluid connection via the first refrigerant passage channel with the second refrigerant outlet of the second block, the second refrigerant outlet of the second block is in fluid connection with the fourth refrigerant inlet of the expansion valve and the fourth refrigerant outlet of the expansion valve is in fluid connection with the third refrigerant inlet of the second block.
